Lighting fixture commissioning based on powerline signaling techniques

ABSTRACT

An intelligent lighting system may be installed using pre-existing electrical wiring, such as in a construction or retrofit environment. An intelligent lighting controller and an intelligent lighting fixture may be connected via electrical wiring that is configured for transmitting AC power signals. A commissioning signal may be transmitted to the intelligent lighting fixtures via the electrical wiring. In some cases, the intelligent lighting controller modifies portions of the AC power signal to indicate the commissioning signal. The intelligent lighting fixtures may receive the commissioning signal via the electrical wiring. In some cases, each intelligent lighting fixture that is connected to the electrical wiring, such as each intelligent lighting fixture on a lighting circuit in a room, receives the commissioning signal.

RELATED APPLICATIONS

The present application claims priority to U.S. application Ser. No.16/589,545 for “Lighting Fixture Commissioning Based on PowerlineSignaling Techniques” filed Oct. 1, 2019, which is incorporated byreference herein in its entirety.

TECHNICAL FIELD

This disclosure relates generally to the field of lighting fixtures, andmore specifically relates to commissioning of programmable lightingfixtures.

BACKGROUND

An intelligent lighting fixture may provide controllable lightingeffects in an environment. For example, the intelligent lighting fixturemay provide lighting effects such as dimming, color selection,correlated color temperature selection, timed lighting, multiple scenes,or other suitable lighting effects. In some cases, an intelligentlighting fixture is commissioned, such as by logically pairing theintelligent lighting fixture with an intelligent lighting controller. Insome cases, the intelligent lighting fixture may require commissioningto perform one or more of the controllable lighting effects.

Commissioning an intelligent lighting fixture may include transmittingone or more communications between the intelligent lighting fixture andan intelligent lighting controller. In some cases, the commissioningcommunications identify which intelligent lighting fixtures arecontrolled by a particular intelligent lighting controller. Existingcommissioning techniques may be initiated by depressing a button on thelighting device that is being commissioned. However, this technique maycause difficulties for a person who is performing the commissioning. Forexample, a lighting technician may need to move a ladder to eachlighting fixture that is being commissioned, and to climb up and downthe ladder multiple times in order to depress the button. In addition,existing commissioning techniques may require additional components,such as low-voltage wiring or power line communication (“PLC”)transceivers, and the size, complexity, or installation of thesecomponents may increase the cost of these existing commissioningtechniques.

Another existing commissioning technique may include transmitting acommunication via radio frequency (“RF”) signals. However, a lightingfixture that is in close proximity to an RF controller may be difficultto assign to a different controller, if the user wishes to assign thefixture to a different group or zone. In addition, an RF signal may bevulnerable to interference, in particular during the initialcommissioning of an intelligent lighting fixture. The RF signal may besubject to accidental or malicious interference, resulting in thecommissioning being error-prone or vulnerable to an attack by amalicious actor.

It is desirable to develop commissioning techniques that are simple fora person to perform, without requiring movement between lightingfixtures, and without requiring physical contact with or visiblefeedback from the lighting fixtures being commissioned. It is alsodesirable to develop commissioning techniques that do not requireinstallation of additional wires or other components. It is alsodesirable to develop commissioning techniques that are resilient againstinterference.

SUMMARY

According to certain implementations, an intelligent lighting controllerand an intelligent lighting fixture are connected via high-voltageelectrical wiring. The electrical wiring may be configured fortransmitting AC power signals. The intelligent lighting controllermodifies a waveform of the AC power signal. The modification may includeomitting a sequence of portions of the waveform, such that the sequenceof omitted portions indicates a commissioning signal. The intelligentlighting fixture may receive the modified AC power signal via theelectrical wiring. In addition, the intelligent lighting fixture mayenter a commissioning mode responsive to determining that the omittedsequence of waveform portions indicates the commissioning signal. Insome cases, the intelligent lighting controller modifies an additionalportion of the AC power signal by omitting an additional sequence ofportions of the waveform, such that the additional omitted sequenceindicates a commissioned group. The intelligent lighting fixture mayjoin the commissioned group responsive to determining that theadditional omitted sequence of waveform portions indicates thecommissioned group.

These illustrative implementations are mentioned not to limit or definethe disclosure, but to provide examples to aid understanding thereof.Additional implementations are discussed in the Detailed Description,and further description is provided there.

DETAILED DESCRIPTION

As discussed above, prior commissioning techniques for intelligentlighting fixtures do not provide a commissioning process that is bothsecure and physically simple to perform. Certain implementationsdescribed herein provide for powerline commissioning techniques that maybe initiated by a technician at an intelligent lighting controller,without requiring physical access to each intelligent lighting fixture.These techniques may improve speed and efficiency for performing thecommissioning, as well as improving comfort for the technician, such asby eliminating or reducing a need to climb ladders, shift ceilingpanels, or other physical steps to access or visually check eachintelligent lighting fixture.

In addition, the described powerline commissioning techniques mayimprove security for the commissioning process, such as by reducing oreliminating wireless signals that are transmitted to or from anuncommissioned intelligent lighting fixture. Security of an intelligentlighting system may be improved by eliminating wireless transmissionsfrom an uncommissioned lighting fixture that is advertising its presenceor availability to join an intelligent lighting system. For example,initiating commissioning via a powerline signaling technique mayeliminate a scanning process of uncommissioned intelligent lightingfixtures, such as scanning for lighting fixtures via wirelesstransmissions. The described techniques may reduce errors resulting froma lighting fixture responding to an inappropriate wireless commissioningsignal (e.g., transmitted from a different floor of a building). Inaddition, the described techniques may reduce opportunity for deliberateinterference from an outside system, such as malicious interference froma party seeking to gain access to the intelligent lighting system.

The following examples are provided to introduce certain implementationsof the present disclosure. An intelligent lighting system may beinstalled in an area, such as a room that is being retrofitted with theintelligent lighting system. In installation area, an intelligentlighting controller and an intelligent lighting fixture may be connectedvia high-voltage electrical wiring that is configured for transmittingAC power signals. The electrical wiring may connect multiple intelligentlighting fixtures in the installation area, such as via a lightingcircuit in the room that is being retrofitted. A commissioning processmay be initiated at the intelligent lighting controller, such as inresponse to an input (e.g., by a technician using the intelligentlighting controller). The intelligent lighting controller modifies theAC power signal by omitting a sequence of portions of a waveform of theAC power signal. The sequence of omitted portions may indicate acommissioning signal. The intelligent lighting fixture may receive themodified AC power signal via the electrical wiring. In addition, theintelligent lighting fixture may enter a commissioning mode responsiveto determining that the omitted sequence of waveform portions indicatesthe commissioning signal. Subsequent to providing the modified AC powersignal, the intelligent lighting controller modifies an additionalportion of the AC power signal by omitting an additional sequence ofportions of the waveform, such that the additional omitted sequenceindicates a commissioned group. The intelligent lighting fixture mayjoin the commissioned group responsive to receiving the additionalomitted sequence of waveform portions. In some cases, responsive toreceiving the commissioning signal via the electrical wiring, theintelligent lighting fixture transmits a verification signal via awireless technique, such as to verify information in the commissioningsignal.

Referring now to the drawings, FIG. 1 is a diagram depicting an exampleof an environment 100 in which an intelligent lighting system may becommissioned via powerline commissioning techniques. In the environment100, one or more intelligent lighting fixtures, such as a plurality ofintelligent lighting fixtures 170, and at least one intelligent lightingcontroller, such as the intelligent lighting controller 120, areinstalled in an area of the environment 100. In FIG. 1, the installationarea is depicted as a room 105, but other implementations are possible.For example, the installation area may include an interior area of abuilding (e.g., rooms, hallways, maintenance areas), an exterior area(e.g., entryways, accent lighting), areas that are not associated with abuilding (e.g., parking lots, gardens), or any other suitable area (orcombination of areas) in which an intelligent lighting system may beinstalled.

Each of the intelligent lighting fixtures 170 may be capable ofproviding programmable lighting effects. Examples of programmablelighting effects include (without limitation) dimming, color selection,correlated color selection, timed lighting, multiple scenes, or othersuitable programmable lighting effects. In some cases, programmablelighting effects include effects that are provided based on input fromone or more sensors, (e.g., occupancy sensors, ambient light sensors,temperature sensors). In addition, the intelligent lighting controller120 may be capable of providing instructions to one or more of theintelligent lighting fixtures 170. For example, the lighting controller120 may provide to the lighting fixtures 170 digital instructions toprovide a programmable lighting effect. In some cases, the intelligentlighting controller 120 is configured to receive instructions describingthe one or more programmable lighting effects. For example, the lightingcontroller 120 may receive instructions from a component in anintelligent lighting system (e.g., a central control panel, a securitysystem). In some cases, the lighting controller 120 may transmit some orall of the received instructions to the intelligent lighting fixtures170.

In some cases, the environment 100 may have electrical wiring, such aselectrical wiring 180. The electrical wiring 180 may provide anelectrical pathway between the intelligent lighting controller 120 andthe intelligent lighting fixtures 170. In some cases, the electricalwiring 180 is a conductor for an alternating current (“AC”) powersignal. For example, an AC power source 110 may provide the AC powersignal to the lighting controller 120. The electrical wiring 180 mayconduct the AC power signal between the lighting controller 120 and eachof the lighting fixtures 170. In some cases, the AC power signal may beconsidered a high-voltage power signal having a voltage that is suitablefor powering a residential or business facility (e.g., 120 V, 240 V,277V).

In some implementations, the environment 100 is a retrofit environment,such as an installation area in which light fixtures and light switchesare replaced with an intelligent lighting system. For example, one ormore of the intelligent lighting fixtures 170 may replace a previouslighting fixture that is incapable of providing a programmable lightingeffect. In addition, the intelligent lighting controller 120 may replacea previous lighting switch that is incapable of providing digitalinstructions to a lighting fixture. In the example retrofit environment,the electrical wiring 180 may include legacy wiring, such as wiringpresent in the walls of the room 105 prior to replacement of a lightingfixture or lighting switch. The electrical wiring 180 may connect eachlighting fixture on a lighting circuit in the room 105, such as a legacylighting circuit that connects previous lighting fixtures (e.g.,replaced by the intelligent lighting fixtures 170) to a previous lightswitch (e.g., replaced by the intelligent lighting controller 120).

In some implementations, a commissioning process may be performed forthe intelligent lighting fixtures 170. The commissioning process mayinclude transmission of one or more commissioning signals to theintelligent lighting fixtures 170 from the intelligent lightingcontroller 120. The commissioning signals may indicate an associationbetween the intelligent lighting fixtures 170 and the intelligentlighting controller 120, such as an association that assigns theintelligent lighting fixtures 170 to a group that is controlled bydigital instructions received from the intelligent lighting controller120. Responsive to receiving the commissioning signals, each of thelighting fixtures in the intelligent lighting fixtures 170 may performone or more operations related to joining the commissioned group for theintelligent lighting controller 120. Subsequent to joining thecommissioned group, the intelligent lighting fixtures 170 may provideprogrammable lighting effects based on digital instructions receivedfrom the intelligent lighting controller 120.

As used herein, the term “group” refers to one or more intelligentlighting fixtures that are configured to provide programmable lightingeffects based on digital instructions received from a particularintelligent lighting controller that is associated with the group offixtures. Commissioned groups of intelligent lighting fixtures mayprovide an understandable way (e.g., readily understood by a technicianor user of the lighting system) to distribute digital instructions tocollections of fixtures. For example, an intelligent lighting fixturewithin a group may respond to group instructions (e.g., an instructionindicating “power on” for all group fixtures). In addition, anintelligent lighting fixture within a group may be assigned to one ormore zones (e.g., sub-groups), and may respond to zone instructions(e.g., an instruction indicating “dim to 50%” for all fixtures in azone). In some cases, a particular intelligent lighting fixture that isincluded in a commissioned group may disregard instructions receivedfrom another intelligent lighting controller that is unassociated withthe particular fixture's group. For example, if the particular lightingfixture that is capable of receiving instructions that are broadcast tomultiple groups (e.g., wirelessly broadcast, wired broadcast), theparticular lighting fixture may disregard the broadcast instructionsresponsive to determining that the broadcast instructions are notassociated with the particular fixture's group.

In the environment 100, one or more commissioning signals for theintelligent lighting fixtures 170 may be transmitted via the electricalwiring 180. For example, the intelligent lighting controller 120 maymodify an AC power signal received from the AC power source 110. Themodification may include omitting a portion, or multiple portions, ofthe waveform of the AC power signal. In some cases, the omitted portionsmay represent a commissioning signal. The intelligent lightingcontroller 120 may transmit the modified waveform to each of theintelligent lighting fixtures 170 that are configured to receive powervia the wiring 180. Responsive to receiving the modified power signal,each of the intelligent lighting fixtures 170 may perform one or moreoperations related to commissioning, such as entering a commissioningmode or joining a commissioned group. The commissioning signal may bereceived by each lighting fixture that is connected via electricalwiring 180, such as each lighting fixture connected via the legacylighting circuit in the room 105.

In some cases, a commissioning process in the environment 100 mayinclude multiple modifications to a power signal. For example, theintelligent lighting controller 120 may perform a first modification ofthe AC power signal. The first modification may include omitting a firstportion, or sequence of portions, of the AC power signal. Each of theintelligent lighting fixtures 170 may receive the AC power signal withthe first modification via the electrical wiring 180. Responsive todetermining that the AC power signal has the first modification, theintelligent lighting fixtures 170 may perform one or more operationsrelated to commissioning. For example, one or more of the intelligentlighting fixtures 170 may enter a commissioning mode, in which arespective intelligent lighting fixture is configured to modify itsrespective commissioned group. In some cases, an intelligent lightingfixture that has entered commissioning mode may perform one or moreadditional operations related to entering the mode, such as emittinglight at a predetermined level (e.g., terminating a programmed dimmingor color lighting effect), providing a visual indication of the mode(e.g., flashing a light emitter, illuminating an indicator LED), orother suitable operations related to entering a commissioning mode.

In addition, the intelligent lighting controller 120 may perform asecond modification of the AC power signal. The second modification mayinclude omitting a second portion, or sequence of portions, of the ACpower signal. The first and second modification may, but need not, havea similar pattern of omitted waveform portions. Each of the intelligentlighting fixtures 170 may receive the AC power signal with the secondmodification via the electrical wiring 180. Responsive to determiningthat the AC power signal has the second modification, the intelligentlighting fixtures 170 may perform one or more additional operationsrelated to commissioning. For example, each of the intelligent lightingfixtures 170 may identify, based on the second modification, acommissioned group that is associated with the intelligent lightingcontroller 120. In addition, one or more of the intelligent lightingfixtures 170 may modify its respective commissioned group, such as byjoining the identified commissioned group associated with theintelligent lighting controller 120. In some cases, an intelligentlighting fixture that has identified the commissioned group may performone or more additional operations related to modifying a commissionedgroup, such as performing a security check or other verification of themodification. In some cases, the verification may include one or moresignals that are not transmitted via the electrical wiring 180, such asa wireless verification transmission that is provided to or receivedfrom the intelligent lighting controller 120.

In some implementations, commissioning signals transmitted via theelectrical wiring 180 indicate a Level 1 commissioning, which assignsthe intelligent lighting fixtures 170 to a group that is controlled bythe intelligent lighting controller 120. In some cases, additionalcommissioning signals (or other control signals) that indicate a Level 2commissioning, such as an effect configuration signal, are provided tothe intelligent lighting fixtures 170. The Level 2 commissioning mayconfigure behaviors or actions performed by the intelligent lightingfixtures 170, such as assignment to a particular zone (e.g., windowlighting, desk lighting) or producing a particular lighting effect(e.g., dimming, nighttime mode). The Level 2 commissioning may indicateprogrammable lighting effects that are configured to be implementedbased on input from one or more sensors, such as an effect configurationsignal that indicates a lighting effect provided in response to an inputfrom an occupancy sensor. In some implementations, the Level 2commissioning may indicate a modification of a Level 1 commissioning.For example, the intelligent lighting controller 120 may send, to thelighting fixtures 170, a modified AC power signal that includes a Level1 commissioning signal assigning the lighting fixtures 170 to a groupassociated with the controller 120. In addition, the intelligentlighting controller 120 may send, to a particular one of the lightingfixtures 170, a Level 2 commissioning signal that assigns the particularlighting fixture to an additional group. In some cases, the additionalgroup does not include the controller 120. Subsequent to being assignedto the additional group, the particular lighting fixture may provideprogrammable lighting effects based on digital instructions receivedfrom an additional intelligent lighting controller in the additionalgroup. In some cases, the particular lighting fixture may disregardinstructions received from the intelligent lighting controller 120, suchas if the additional group does not include the controller 120.

In some implementations, the Level 1 commissioning is indicated via oneor more modifications to an AC power signal, such as the modified powersignal transmitted via the electrical wiring 180. In addition, the Level2 commissioning is indicated via one or more signals transmitted via anadditional transmission channel that does not include the electricalwiring 180, such as a wireless transmission channel or low-voltagewiring. For example, the intelligent lighting controller 120 may send tothe lighting fixtures 170 a modified AC power signal via the electricalwiring 180. The modified AC power signal may indicate a Level 1commissioning signal, such that the lighting fixtures 170 enter acommissioning mode responsive to the modified AC power signal.Subsequently, the intelligent lighting controller 120 may send to thelighting fixtures 170 an effect configuration signal via an additionalcommunication channel that excludes the electrical wiring 180. Forexample, the effect configuration signal may be sent wirelessly, such asvia one or more antennas of the controller 120 or the fixtures 170, orvia an additional wired channel, such as low-voltage wiring. The effectconfiguration signal may indicate a Level 2 commissioning signal, suchthat, based on digital instructions included in the effect configurationsignal, the lighting fixtures 170 are configured to provide one or moreprogrammable lighting effects.

In some implementations, security data may be transmitted via amodification of the AC power signal. For example, the intelligentlighting controller 120 may perform an additional modification of the ACpower signal (such as, but not limited to, a modification indicating averification check or a Level 2 commissioning). The additionalmodification may omit an additional portion, or sequence of portions, ofthe AC power signal. In addition, the additional modification mayindicate security data, such as security data that is associated withthe intelligent lighting controller 120, the group controlled by thecontroller 120, or both. In some cases, the security data may includeone or more of information describing a secured communications network(e.g., an address, a login/password), a cryptographic key or key pair,or other information that is usable to secure communications betweencomponents in an intelligent lighting network. Each of the intelligentlighting fixtures 170 may receive the AC power signal with theadditional modification via the electrical wiring 180. Responsive todetermining that the AC power signal has the additional modification,the intelligent lighting fixtures 170 may transmit a communication thatis secured using the indicated security data. For example, each of theintelligent lighting fixtures 170 may transmit, to the intelligentlighting controller 120, a secured communication, such as a securedcommunication that is encrypted using a cryptographic key indicated bythe additional modification. In some cases, the secured communication istransmitted via an additional communication channel that excludes theelectrical wiring 180. For example, the secured communication may besent wirelessly, such as via one or more antennas of the controller 120or the fixtures 170, or via an additional wired channel, such aslow-voltage wiring.

FIG. 2 is a diagram depicting an example implementation of anintelligent lighting controller 220 and a plurality of intelligentlighting fixtures 270 connected via electrical wiring 280. Theintelligent lighting fixtures 270 may include multiple fixtures, such asan intelligent lighting fixture 270 a, an intelligent lighting fixture270 b, through an intelligent lighting fixture 270 n. The intelligentlighting controller 220, the intelligent lighting fixtures 270, and theelectrical wiring 280 may be included in a retrofit environment or otherinstallation area, such as the environment 100. In some cases, theelectrical wiring 280 is legacy wiring.

The electrical wiring 280 may be configured to transmit high-voltageelectrical power, such as an AC power signal received from an AC powersource 210. The electrical wiring 280 may include a neutral line 283that provides an electrical pathway between the AC power source 210 andthe intelligent lighting fixtures 270. In some implementations, theneutral line 283 may be connected to the intelligent lighting controller220, such that the neutral line 283 provides an electrical pathwaybetween the AC power source 210 and the controller 220, and between thecontroller 220 and the intelligent lighting fixtures 270.

In addition, the electrical wiring 280 may include a hot line 287 a thatprovides an electrical pathway between the AC power source 210 and theintelligent lighting controller 220, and a hot line 287 b that providesan electrical pathway between the intelligent lighting controller 220and the intelligent lighting fixtures 270. The hot lines 287 a and 287 bare collectively referred to herein as hot line 287. In some cases, theelectrical wiring 280 may include an additional line that is designatedas a ground line.

In FIG. 2, the intelligent lighting controller 220 is configured tocarry power that is transmitted on the hot line 287. In some cases, theintelligent lighting controller 220 includes a switch 230 that isconfigured to allow or prevent transmission of the AC power signaltransmitted on the hot line 287. The switch 230 may include a transistor(e.g., MOSFET, BJT, IGBT, SiCFET), a relay, a thyristor, or otherelectrical component (or combination of components) suitable to allowand prevent transmission of a high-voltage AC power signal. In addition,the intelligent lighting controller 220 may include one or more of amicroprocessor 240, a radio 260, an antenna 265, and a power supply 225.In some cases, the intelligent lighting controller 220 may include oneor more user interface components, such as a button, a touchscreen, atoggle, a slider, or any other suitable user interface component (orcombination of components). In addition, the intelligent lightingcontroller 220 may include (or be configured to connect to) one or moresensors, such as an occupancy sensor, an ambient light sensor, or othersuitable sensor types.

In some implementations, the switch 230 may modify the AC power signalthat is received on the hot line 287 a, such as via a power input 237.In addition, the switch 230 may transmit the modified power signal onthe hot line 287 b, such as via a power output 239. In some cases, themodification to the power signal is based on an indication received fromthe microprocessor 240, such as a digital instruction signal indicatingthe modification. The indication may be received by the switch 230 via acontrol input 233. In some cases, the digital instruction includes acommissioning signal, such as an instruction for an intelligent lightingfixture to enter a commissioning mode. The microprocessor 240 mayprovide the digital instruction responsive to an input to theintelligent lighting controller 220, such as an input received via theradio 260, or via a user interface component of the intelligent lightingcontroller 220, or via another suitable input technique. In some cases,the digital instruction indicates the modification for the power signal,such as a digital instruction having bits representing portions of thepower signal that are to be omitted. Based on the digital instruction orother indication from the microprocessor 240, the switch 230 modifiesone or more portions of the waveform for the AC power signal receivedvia the hot line 287 a. In some cases, the modified waveform includes asequence of omitted waveform portions. In addition, the omitted sequencemay indicate the commissioning signal. The modified waveform may betransmitted to the intelligent lighting fixtures 270 via the hot line287 b.

In some cases, each of the intelligent lighting fixtures 270 determinesthat the AC power signal received via the line 287 b includes amodification. For example, a receiver 272 included in the lightingfixture 270 a monitors the AC power signal present on the line 287 b.Based on the monitoring, the receiver 272 may detect that the AC powersignal is modified to include the sequence of omitted waveform portions.In addition, the receiver 272 may provide an indication of the omittedsequence, such as to a microprocessor 275. The processor 275 maydetermine that the sequence indicates the commissioning signal.Responsive to determining that the modified AC power signal indicatesthe commissioning signal, the processor 275 performs an operationrelated to commissioning, such as entering a commissioning mode. Whileoperating in the commissioning mode, the processor 275 may perform oneor more additional operations, such as providing a command to a lightingdriver 274, which may adjust a power current supplied to a lightingemitter 276. Each of the fixtures 270 a through 270 n may receive themodified power signal via the line 287 b. In addition, each of thefixtures 270 a through 270 n may respond to the commissioning signal,such as by entering commissioning mode.

In some implementations, the switch 230 may apply additionalmodifications to additional portions of the AC power signal received onthe line 287 a. For example, subsequent to modifying the AC power signalto indicate the commissioning signal, the switch 230 may receive fromthe microprocessor 240 an additional digital instruction (or otherindication) that indicates an additional commissioning signal. Forexample, the additional commissioning signal may indicate one or more ofan identification of the intelligent lighting controller 220, anidentification of a commissioned group associated with the intelligentlighting controller 220, or other information related to commissioning.Based on the additional digital instruction, the switch 230 modifies oneor more portions of the AC waveform received via the line 287 a, such asby omitting an additional sequence of waveform portions to indicate theadditional commissioning signal The additional modified waveform may betransmitted to the intelligent lighting fixtures 270 via the line 287 b.

The receiver 272 may detect the additional modified waveform of the ACpower signal. In addition, the receiver may provide an indication of theadditional omitted sequence, such as to the processor 275. Responsive toreceiving the indication of the additional omitted sequence, theprocessor 275 determines that the additional sequence indicates theadditional commissioning signal. In addition, responsive to determiningthat the additional commissioning signal identifies the commissionedgroup of the intelligent lighting controller 220, the processor 275performs one or more additional operation related to commissioning, suchas modifying the commissioned group assigned to the fixture 270 a. Eachof the fixtures 270 a through 270 n may receive the additionalmodification of the power signal via the line 278 b. In addition, eachof the fixtures 270 a through 270 n may respond to the additionalcommissioning signal, such as by each modifying the respectivecommissioned group of the respective fixture.

In some implementations, one or more of the intelligent lightingfixtures 270 performs additional operations related to modifying arespective commissioned group, such as verification operations. Theverification operations may include transmission of one or more signalsvia an additional transmission channel that does not include theelectrical wiring 280. For example, responsive to determining that thepower signal on line 287 b is modified to indicate the commissioningsignal or the additional commissioning signal, the lighting fixture 270a may transmit a verification signal via an antenna 273. Although FIG. 2depicts the fixture 270 a as having an antenna 273, otherimplementations are possible, such as transmission of a verificationsignal via low-voltage wiring that is separate from the electricalwiring 280. The verification signal may indicate that a commissioningsignal has been received by the fixture 270. In addition, theverification signal may indicate the commissioned group identified bythe commissioning signal. In some cases, the verification signal may betransmitted to the intelligent lighting controller 220. For example, theintelligent lighting controller 220 may receive the verification signalvia the antenna 265. In addition, the verification signal may betransmitted to an additional component in an intelligent lightingsystem, such as a central control panel or an additional intelligentlighting controller. The lighting fixture 270 a may receive averification response via the antenna 273, such as a verificationresponse transmitted by the intelligent lighting controller 220 via theantenna 265. In some cases, the lighting fixture 270 a may modify itscommissioned group responsive to receiving the verification response(e.g., subsequent to a confirmation of the commissioning signal or thecommissioned group).

In some implementations, a modified AC power signal may include asequence of omitted portions of the power signal waveform. The sequenceof omitted waveform portions may indicate, for example, a digitalinstruction received by a switch in an intelligent lighting controller,such as the switch 230. In some cases, the sequence of omitted waveformportions may include a pattern that indicates a commissioning signal. Inaddition, the sequence of omitted waveform portions may include a firstpattern indicating a first bit and a second pattern indicating a secondbit, such that the commissioning signal is indicated by a series of thefirst and second patterns. Additional patterns may be used, such asrespective patterns indicating a high bit, a low bit, a start bit, or anend bit.

FIG. 3 is a diagram depicting examples of a sequence of omitted waveformportions. The examples in FIG. 3 are non-limiting, and other sequencesof omissions may be used without departing from the implementations andtechniques described herein. The depicted waveforms 302, 304, 306, and308 include example portions from an AC power signal having aroot-mean-squared (“RMS”) voltage of approximately 120 V, a peak voltageof approximately 170 V, and a frequency of approximately 60 Hz, butother implementations are possible, including other peak-to-peakvoltages and other frequencies. The waveform 302 depicts an unmodifiedportion of the example AC power signal. The unmodified portion includessix complete (e.g., non-omitted) cycles having an amplitude from about−170 V to about +170 V, over a time duration from about t=0 sec to aboutt=0.1 sec.

The waveform 304 depicts an example of a sequence of omitted waveformportions. The waveform 304 includes a complete cycle having an amplitudefrom about −170 V to about +170 V, followed by two cycles having omittedpositive portions (e.g., omitted from about 0 to 170 V) and non-omittednegative portions (e.g., non-omitted from about −170 to 0 V). Theexample sequence of a complete cycle followed by two cycles havingomitted positive portions is repeated once in the waveform 304.

The waveform 306 depicts an additional example of a sequence of omittedwaveform portions. The waveform 306 includes a cycle having an omittedinitial positive half, followed by two cycles having omitted positiveportions and non-omitted negative portions. The example sequence of acycle having an omitted initial positive half followed by two cycleshaving omitted positive portions is repeated once in the waveform 306.

The waveform 308 depicts an additional example of a sequence of omittedwaveform portions. The waveform 308 includes a cycle having an omittedlatter positive half, followed by two cycles having omitted positiveportions and non-omitted negative portions. The example sequence of acycle having an omitted latter positive half followed by two cycleshaving omitted positive portions is repeated once in the waveform 308.

In some cases, the example sequences depicted in waveforms 304, 306, and308 may be used as patterns indicating bits. For example, the examplesequence in waveform 304 may indicate a start bit (e.g., a bitindicating a beginning of a sequence of bits). In addition, the examplesequence in waveform 306 may indicate a high bit, and the examplesequence in waveform 308 may indicate a low bit. In someimplementations, a modification to an AC power signal may include one ormore of the example sequences, such that a commissioning signal isindicated by the included example sequences (e.g., a series of bits).The examples depicted in FIG. 3 are non-limiting, and other omitted (ornon-omitted) sequences may be used without departing from theimplementations and techniques described herein, such as omissions ofhalf waves, full waves, partial waves, portions of positive waves,portions of negative waves, or any other omission or combination ofomissions on an AC power signal.

In some implementations, an intelligent lighting controller includes oneor more electrical components that are configured to modify an AC powersignal. In addition, an intelligent lighting fixture includes one ormore electrical components that are configured to determine amodification of a received AC power signal. FIG. 4 is a diagramdepicting an example configuration of electrical components that may beused to modify an AC power signal. In FIG. 4, an AC power source 410, anintelligent lighting controller 420, and an intelligent lighting systemreceiver 472 are connected via electrical wiring 480. The intelligentlighting controller 420, the receiver 472, and the electrical wiring 480may be included in a retrofit environment or other installation area,such as described in regards to FIGS. 1 and 2. In some cases, theelectrical wiring 480 is legacy wiring. The receiver 472 may be includedin a component of an intelligent lighting system, such as an intelligentlighting fixture, an intelligent sensor, an intelligent lighting driver,or another intelligent lighting component.

The electrical wiring 480 may be configured to transmit high-voltageelectrical power, such as an AC power signal received from the AC powersource 410. The electrical wiring 480 may include a neutral line 483that provides an electrical pathway between the AC power source 410, theintelligent lighting controller 420, and the receiver 472. In someimplementations, the intelligent lighting controller 420 may omit aneutral line, such that the neutral line provides an electrical pathwaybetween the AC power source 410 and the receiver 472. In FIG. 4, theelectrical wiring 480 may include a hot line 487 a that provides anelectrical pathway between the AC power source 410 and the intelligentlighting controller 420, and a hot line 487 b that provides anelectrical pathway between the intelligent lighting controller 420 andthe receiver 472. The hot lines 487 a and 487 b are collectivelyreferred to herein as hot line 487. In some cases, the electrical wiring480 may include an additional line that is designated as a ground line.

The AC power source 410 may include at least one voltage source, such asa voltage source V1, that is configured to provide an AC power signalvia the hot and neutral lines 487 and 483. The AC power signal may betransmitted to a switch that is included in the intelligent lightingcontroller 420, such as a metal-oxide semiconductor field-effecttransistor (“MOSFET,” “FET”) U1 that is configured to perform switchingon the hot line 487. In some implementations, the switch included in thecontroller 410 may include a MOSFET, a bipolar-junction transistor(“BJT”), a relay, an insulated-gate bipolar transistor (“IGBT”), asilicon-controlled rectifier (“SCR”), a bidirectional triode thyristor(“TRIAC”), or any other component or combination of components that issuitable to perform switching of the AC power signal. In some cases, theFET U1 may have a different orientation (e.g., positions of source anddrain may be reversed relative to lines 487 a and 487 b), such as ifnegative portions of an AC waveform are omitted.

The intelligent lighting controller 420 may also include a digitalvoltage source V2, which is configured to provide a low-voltage controlsignal to the FET U1. In some cases, the low-voltage control signal maybe provided via a microprocessor, such as a microprocessor that includes(or is configured to provide) the digital voltage source V2. In theintelligent lighting controller 420, a resistor R2 may be connectedbetween the digital voltage source V2 and the gate of the FET U1. Insome cases, the resistor R2 may have a value of about 10Ω to about 220Ω.

Based on the low-voltage control signal received from the digitalvoltage source V2, the FET U1 may modify the AC power signal received online 487 a. For example, the FET U1 may provide or omit portions of thewaveform for the AC power signal, based on whether the FET U1 isswitched open or closed. In addition, the FET U1 may omit the waveformportions in a sequence corresponding to a commissioning signal, such asa sequence of omitted portions representing one or more bits.

The modified AC power signal may be received by the receiver 472 vialine 487 b. The receiver 472 may include one or more electricalcomponents configured to monitor the power signal on line 487 b formodifications. Responsive to determining that the AC power signal online 487 b is modified in a pattern indicating the commissioning signal,the receiver 472 may provide an indication of the modification. Forexample, the receiver 472 may provide an indication to an intelligentlighting system component that includes the receiver 472. In addition,responsive to the indication from the receiver 472, the intelligentlighting system component may perform an operation related tocommissioning.

In some implementations, multiple intelligent lighting system receiversmay be configured to receive commissioning signals, via an AC powersignal, from a particular intelligent lighting controller. FIG. 5 is adiagram depicting an example configuration of electrical components thatmay be used to receive a modified AC power signal. In FIG. 5 anintelligent lighting system receiver 572 is connected to the AC powersource 410 and the intelligent lighting controller 420, such asdescribed in regards to FIG. 4. In FIG. 5, the neutral line 483 mayprovide an electrical pathway between the AC power source 410, theintelligent lighting controller 420, and the receiver 572, and the hotline 487 b may provide an electrical pathway between the intelligentlighting controller 420 and the receiver 572.

In some implementations, the receiver 572 may include an input 577 andan input 578 that are configured to receive an AC power signal. Forexample, the hot line 487 b may be connected at the input 577 and theneutral line 483 may be connected at the input 578. In addition, thereceiver 572 may include one or more sensors that are configured tomonitor an amplitude of the received AC power signal, such as anoptocoupler U2. In some cases, an input to the optocoupler U2 may beconnected to one or more additional components, such as a resistor R1 inseries connection with a diode D1. In some cases, the resistor R1 mayhave a value (e.g., about 220 kΩ) that is suitable to limit currentreceived by the optocoupler U2. In addition, the diode D1 may providecurrent blocking at the input(s) of the optocoupler U2.

In some implementations, the optocoupler U2 may receive an AC powersignal via one or more of the inputs 577 and 578. The received powersignal may be a modified AC power signal, such as an AC signal modifiedby the FET U1 (e.g., as described in regards to FIG. 4), or the receivedpower signal may be an unmodified AC power signal (e.g., not modified bythe intelligent lighting controller 420). The optocoupler U2 may beconfigured to provide an output based on an amplitude of the receivedpower signal. For example, the optocoupler U2 may provide an output whenthe received power signal has an amplitude above a forward voltage level(e.g., about 1.5 V) of a photodiode included in the optocoupler. Inaddition, the optocoupler U2 may withhold the output when the receivedpower signal has an amplitude below the forward voltage level (e.g., thereceived AC signal is negative or around 0V). For example, based on theAC power signal received by the receiver 572, the optocoupler U2 mayprovide the output when the AC power signal has an amplitude greaterthan 0 volts and withhold the output when the AC power signal has anamplitude around or below 0 volts.

In some cases, an output of the receiver 572 may be based on the outputof the optocoupler U2. For example, the receiver 572 may include adigital voltage source V3 that is connected between a collector and anemitter of a photodetector included in the optocoupler U2. In somecases, the digital voltage source V3 may be connected to one or moreadditional components, such as one or more of a series connection to aresistor R3 or a parallel connection to a capacitor C1. In some cases,the resistor R3 and the capacitor C1 may have respective values (e.g.,about 47 kΩ, about 1 μF) that are suitable to provide a output voltageat an output 573 of the receiver 572.

Responsive to the output of the optocoupler U2 (e.g., the received powersignal has an amplitude above the forward voltage level), the receiver572 may provide a first voltage level at the output 573, such as avoltage level of about 0 V. In addition, responsive to the optocouplerU2 withholding the output (e.g., the received power signal has anamplitude below the forward voltage level), the receiver 572 may providea second voltage level at the output 573, such as a voltage level ofabout 3.3 V, 5 V, or any other suitable low-voltage digital level. Basedon an AC waveform of the received power signal, the receiver 572 mayprovide an output signal indicating positive or non-positive portions ofthe waveform. For example, the receiver 572 may provide, to anintelligent lighting system component, an output signal indicatingomitted portions of the AC waveform. Based on a pattern of the omittedportions indicated by the receiver 572, such as a pattern indicating acommissioning signal, the intelligent lighting system component mayperform an operation, such as an operation related to commissioning.

FIG. 6 is a diagram depicting an additional example configuration ofelectrical components that may be used to receive a modified AC powersignal. In FIG. 6 an intelligent lighting system receiver 672 isconnected to the intelligent lighting controller 420 and the voltagesource V1 included in the AC power source 410, such as described inregards to FIG. 4. In FIG. 6, the neutral line 483 may provide anelectrical pathway between the voltage source V1, the intelligentlighting controller 420, and the receiver 672, and the hot line 487 bmay provide an electrical pathway between the intelligent lightingcontroller 420 and the receiver 672.

In some implementations, the receiver 672 may include an input 677 andan input 678 that are configured to receive an AC power signal. Forexample, the hot line 487 b may be connected at the input 677 and theneutral line 483 may be connected at the input 678. The receiver 672 mayinclude a rectifier 678 that is configured to adjust a negative voltagevalue of the received power signal to a positive voltage value. Inaddition, the receiver 672 may include a voltage divider 679 that isconfigured to reduce an amplitude of the received power signal.

The receiver 672 may include one or more sensors that are configured tomonitor the received AC power signal for zero crossings, such as anoptocoupler U3. In some cases, an input to the optocoupler U3 may beconnected to one or more additional components, such as one or more of abipolar junction transistor (“BJT”) Q1, a resistor R4, a capacitor C3,or one or more diodes D5 and D6. In FIG. 6, the resistor R4 may have avalue (e.g., about 100Ω) that is suitable to limit current received bythe optocoupler U3. In addition, the capacitor C3 may have a value(e.g., about 0.33 g) that is suitable to store energy from the receivedpower signal, such as energy sampled from the output of voltage divider679. The energy stored by capacitor C3 may be released through theoptocoupler U3, BJT Q1, and resistor R4 when the amplitude of thesampled signal is less than a bias voltage (e.g., about 14.3 V) on thebase of the BJT Q1. In addition, the diode D5 may provide currentblocking at the input(s) of the optocoupler U3 and/or BJT Q1. In somecases, the diode D6 is a Zener diode, and may provide voltagestabilization, such as by clamping the voltage at the base of BJT Q1.

In some implementations, the optocoupler U3 may receive the energyreleased by capacitor C3, such as when the amplitude of the sampledsignal is less than the bias voltage on BJT Q1. The sampled signal maybe based on a modified AC power signal, such as an AC signal modified bythe FET U1 (e.g., as described in regards to FIG. 4), or on anunmodified AC power signal (e.g., not modified by the intelligentlighting controller 420). The optocoupler U3 may be configured toprovide an output based on the released energy. For example, theoptocoupler U3 may provide an output when the base voltage on Q1 islower than voltage across C3 by about 0.7 V. In addition, theoptocoupler U3 may withhold the output when the base voltage on Q1 islower than voltage across C3 (e.g., while C3 is charging). For example,based on the AC power signal received by the receiver 672, theoptocoupler U3 may provide an output pulse when the AC power signal hasa non-zero amplitude and withhold the output pulse when the AC powersignal has a zero amplitude (e.g., a zero-cross pulse that is releasedat zero crossings of the AC waveform).

In some cases, an output of the receiver 672 may be based on the outputof the optocoupler U3. For example, the receiver 672 may include adigital voltage source V4 that is connected at a collector of aphotodetector included in the optocoupler U3. In some cases, the digitalvoltage source V4 may be connected to one or more additional components,such as to a resistor R5. An additional resistor R6 may be connectedbetween an output 673 of the receiver 672 and the collector of thephotodetector in optocoupler U3. A capacitor C2 may be connected betweenthe output 673 of the receiver 672 and an emitter of the photodetectorin optocoupler U3. In some cases, the resistors R5 and R6 and thecapacitor C2 may have respective values (e.g., about 10 kΩ, about 100Ω,about 10 nF) that are suitable to provide a output voltage at the output673.

Responsive to the output of the optocoupler U3 (e.g., the AC powersignal has a non-zero amplitude), the receiver 672 may provide a firstvoltage level at the output 673, such as a voltage level of about 0 V.In addition, responsive to the optocoupler U3 withholding the output(e.g., the AC power signal has a zero amplitude), the receiver 672 mayprovide a second voltage level at the output 673, such as a voltagelevel of about 3.3 V or 5 V (or another suitable low-voltage digitallevel). Based on an AC waveform of the AC power signal, the receiver 672may provide an output signal indicating positive or non-positiveportions of the waveform. For example, the receiver 672 may provide, toan intelligent lighting system component, an output signal indicatingomitted portions of the AC waveform. Based on a pattern of the omittedportions indicated by the receiver 672, such as a pattern indicating acommissioning signal, the intelligent lighting system component mayperform an operation, such as an operation related to commissioning.
